Chevrolet LS “Ready To Run” Rotating Assemblies w/ ARP 2000 rod bolt upgrade by Manley Performance

When it comes to building horsepower and torque, you need to start at the bottom and work your way up. Manley rotating assemblies are designed for performance enthusiasts wanting to get the most out of their engines. Their assemblies feature 4340 forged steel crankshaft and H-beam connecting rods, either 7/16 in. ARP 8740 cap screws with a 750 hp rating for LS engines/900 hp for big blocks, or optional ARP 2000 cap screws for up to 1,500 hp. They use 2618 Platinum Series forged aluminum pistons, chromoly premium wrist pins, Total Seal piston rings, and Clevite "H" Series narrowed rods and "P" or "H" Series main engine bearings.
